Additional Inherited Members

Detailed Description

The QExtensionFactory class allows you to create a factory that is able to make instances of custom extensions in Qt Designer.

In Qt Designer the extensions are not created until they are required. For that reason, when implementing a custom extension, you must also create a QExtensionFactory, i.e. a class that is able to make an instance of your extension, and register it using Qt Designer's extension manager.

The QExtensionManager class provides extension management facilities for Qt Designer. When an extension is required, Qt Designer's extension manager will run through all its registered factories calling QExtensionFactory::createExtension() for each until the first one that is able to create a requested extension for the selected object, is found. This factory will then make an instance of the extension.
